These protesters are marching in Milwaukee during Trump's visit

President Trump is in Milwaukee, Wisconsin, this morning to meet with supporters before the Foxconn groundbreaking event. But he'll also be greeted by protesters with the immigrant rights group Voces de la Frontera.

On Twitter, the group says the demonstrators are marching to “demand the abolition of ICE & the Border Patrol” as well as “to resist [President Trump and Gov. Scott Walker’s] plan to put tens of thousands of immigrant families in internment camps.”

CNN’s Ryan Young, who’s at the rally, spoke with a protester who told him that Trump “needs to pay attention to what families and the people across this nation are saying.

"We're united. We're one. What happens to another family is happening to my family. We're not going to let that happen," she said.

When asked why she's protesting, she got emotional and said, “I would want people to fight for my family. It is that simple.”
